SEGGER J-Link Pro: an exhaustive review

SEGGER J-Link PRO an exhaustive review

In our minds, we have always seen SEGGER debugging solutions like a professional but costly tools: a debugger to perform advanced operations but definitely too much for a student. Some time ago we heard about a new version of SEGGER, the J-Link EDU, which is cheaper and addressed virtually to us. It started to take shape the idea of using it as external debugger for these ARM evaluation kit which comes without a debugger.

Some month ago SEGGER proposed a firmware suitable for STM32 Nucleo on-chip debugger which makes J-Link available also for the STM32 ecosystem and they continue reading...

Review of WeSU: a development board for wearable applications.

Wesu Review

At the recent event “ST = Life Augmented”, held in Milan during the Class Digital Experience Week, STMicroelectronics has raffled various development kits, for attendees who enrolled to the event through the Pepite blog. Apart to the famous STM32 Nucleo-64 board and some of its Expansion Board (the STM32 x-Nucleo), the most interesting thing was the development kit for wearable applications, the STEVAL-WESU 1, valued at approximately 50€ and we were lucky to get one for free.

STEVAL-WESU1 stand for ST EVALution WErable Sensor Unit, and is an evaluation kit to test various continue reading...

STM32 Nucleo-144 review

STM32 Nucleo-144 Review

The STM32 Nucleo-144 is a new series of development board by STMicroelectronics. It is the third announced series titled Nucleo. Each Nucleo-144 share the same pin map for each board and features a new connector named ST ZIO which is compatible with Arduino Uno Rev3 connector.

This new series takes his name from the number of pads exhibit by its different MCUs which are all a LQFP144 package. Indeed, the STM32 Nucleo is currently available in 5 configurations we will discuss continue reading...

An object counter using an IR sensor and Arduino

An object counter using an IR sensor and Arduino

In this article we will resume the topic started with in “Detecting obstacle with IR Sensor and Arduino”. More in details, we are going to use the IR sensor like an objects counter.

The counter application is often used for:

counting people traversing a certain passage or entrance. For example, in commercial buildings there are gates which control user access or presence often used to optimize energy consumption; counting objects or merchandise in industrial sector; etc.

A counter can be made not only with IR technology but also with thermal imaging systems that use an continue reading...

Getting started with mikroe BUZZ Click using ChibiOS/HAL

Getting started with mikroe BUZZ Click using ChibiOS/HAL

BUZZ Click is a click board with a mikroBus form factor. It is substantially composed of a piezoelectric speaker having a resonant frequency at 3.8 kHz: this means we should expect best performances at this frequency. Let’s take a look to the principle of operation of DC and AC continue reading...
